GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
1.
Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
SKU 94882
PAGE 2
REV 07e, 08b
2.
Do not operate power tools in explosive atmospheres, such as in the presence
of flammable liquids, gases, or dust. Power tools create sparks which may ignite
the dust or fumes.
3.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
ELECTRICAL SAFETY
4.
Grounded tools must be plugged into an outlet properly installed and grounded
in accordance with all codes and ordinances. Never remove the grounding
prong or modify the plug in any way. Do not use any adapter plugs. Check with
a qualified electrician if you are in doubt as to whether the outlet is properly
grounded. If the tools should electrically malfunction or break down, grounding
provides a low resistance path to carry electricity away from the user.
5.
Double insulated tools are equipped with a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it still does not fit, contact
a qualified electrician to install a polarized outlet. Do not change the plug in
any way. Double insulation
eliminates the need for the three wire grounded
power cord and grounded power supply system.
6.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges,
and refrigerators. There is an increased risk of electric shock if your body is
grounded.
7.
Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
8.
Do not abuse the Power Cord. Never use the Power Cord to carry the tools
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,
sharp edges, or moving parts. Replace damaged Power Cords immediately.
Damaged Power Cords increase the risk of electric shock.
9.
When operating a power tool outside, use an outdoor extension cord marked
“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the
risk of electric shock.
PERSONAL SAFETY
10.
Stay alert. Watch what you are doing, and use common sense when operating
a power tool. Do not use a power tool while tired or under the influence of
drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
SKU 94882
PAGE 3
11.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
12.
Avoid accidental starting. Be sure the Power Switch is off before plugging
in. Carrying power tools with your finger on the Power Switch, or plugging in power
tools with the Power Switch on, invites accidents. Make sure you are prepared to
begin work before turning the Power Switch (62) “ON”.
13.
Remove adjusting keys or wrenches before turning the power tool on. A
wrench or a key that is left attached to a rotating part of the power tool may result
in personal injury.
14.
Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
15.
Always wear eye, hearing, and breathing protection. Wear ANSI-approved
safety impact eye glasses, ANSI-approved hearing protectors, and ANSIapproved dust mask or respirator when using this product. Also, non-skid
safety shoes and a hard hat must be used for appropriate conditions.
TOOL USE AND CARE
16.
Do not use the power tool if the Power Switch does not turn it on or off. Any
tool that cannot be controlled with the Power Switch is dangerous and must be
replaced or repaired.
17.
Disconnect the Power Cord Plug from the power source before making
any adjustments, changing accessories, or storing the tool. Such
preventive safety measures reduce the risk of starting the tool accidentally.
18.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
19.
Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools with a sharp cutting edge are less likely to bind and are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until
repaired.
20.
Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tool’s operation. If damaged, have
the tool serviced before using. Many accidents are caused by poorly maintained
tools.
21.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous when
used on another tool.
SKU 94882
PAGE 4
SERVICE
24.
Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury.
25.
When servicing a tool, use only identical replacement parts. Follow instructions
in the “Inspection, Maintenance, And Cleaning” section of this manual. Use
of unauthorized parts or failure to follow maintenance instructions may create a risk
of electric shock or injury.
GROUNDING
WARNING!
Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualified electrician if you are in doubt as to whether the
outlet is properly grounded. Do not modify the power cord plug provided with
the tool. Never remove the grounding prong from the plug. Do not use the
tool if the power cord or plug is damaged. If damaged, have it repaired by
a service facility before use. If the plug will not fit the outlet, have a proper
outlet installed by a qualified electrician.
GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1.
Tools marked with “Grounding Required” have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If the
tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock.
(See Figure A, next page.)
2.
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached to
an electrically “live” terminal. (See Figure A.)
3.
Your tool must be plugged into an appropriate outlet, properly installed and grounded
in accordance with all codes and ordinances. The plug and outlet should look like
those in the following illustration. (See Figure A page 6.)
SKU 94882
PAGE 5
FIGURE A
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
4.
5.
Tools marked “Double Insulated” do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code. (See Figure B.)
Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B.)
FIGURE B
SKU 94882
PAGE 6
EXTENSION CORDS
1.
Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord.
2.
As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Figure C)
3.
The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Figure C, and Figure D.)
4.
If using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required.
5.
If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Figure C, and Figure D.)
6.
If you are using an extension cord outdoors, make sure it is marked with the suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
8.
Protect your extension cords from sharp objects, excessive heat, and damp or
wet areas.

Vibration Hazard
This tool vibrates during use. Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury, particularly to the hands, arms and
shoulders. To reduce the risk of vibration-related injury:
1.
Anyone using vibrating tools regularly or for an extended period should first be
examined by a doctor and then have regular medical check-ups to ensure medical
problems are not being caused or worsened from use. Pregnant women or people
who have impaired blood circulation to the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any
medical or physical symptoms related to vibration (such as tingling, numbness, and
white or blue fingers), seek medical advice as soon as possible.
2.
Do not smoke during use. Nicotine reduces the blood supply to the hands and
fingers, increasing the risk of vibration-related injury.
3.
Wear suitable gloves to reduce the vibration effects on the user.
4.
Use tools with the lowest vibration when there is a choice between different processes.
5.
Include vibration-free periods each day of work.

OPERATING INSTRUCTIONS
Important - Read before use
This Breaker Hammer may have decreased performance for a brief period at the beginning of each use. This warm-up period lasts approximately 3-5 minutes. This happens
because the grease inside the tool may be thick, preventing the tool from operating at
full efficiency while the motor is cold. This is normal and does not indicate a problem. To
help reduce this effect, store this equipment in temperatures no lower than 50-60° F.
How to turn on the Breaker Hammer
To turn on the Breaker Hammer, flip the Switch (62) shown below in Figure 3.
How to Adjust the impact level of the Breaker Hammer
The Impact level is adjusted by turning the Knob (117). The numbers on the Knob
indicate the level of impact. Number one is the lowest level, seven is the highest
level. See Figure 4.
